Specification of Letters Patent.

Application led July 19, 19056, Serial No. 826,8%. Renewed 16, 1 910. v, Serial No. 561,721.

To all whom, it may concern:

States, and residents, respectively, of New York city, boroughpf Brooklyn,l\lew lYork, and Perth Amboy, Middlesex county, New

Jersey, have invented certain new and useful lniprovementsy in Outlet .or Junction Boxes, of which the following is a specifica-A tion.

rllhis invention relates to improvements in outlet or junction boxes employed in electric circuits for makin branch connections, etc., and has for itsobject to provide simple and elicient means toconceal and protect the outlet openings of the box when not in use, and to permit ready access to said outlet openings for making connections therewith', without danger of injury to the box..v

This invention comprises a box of suitable shape provided with outlet openings inits sides' for the passage of conductors, with a cover provided with a flange adapted to receive and encircle the box and having openings adapted to aline with the outlet openings in the' box, and the openings of the the claims.

Harige are provided with caps or covers detachably connected therewith in such man ner as to normally remain in position to` close the opening of the flange, and to be readily removed by merely pulling them awa from' the flange Without injury thereto.

The invention also comprises the novel details of improvement that will be more fully hereinafter set forth and then pointed out in Reference is to be had to the accompany= ing drawingsl forming part hereof, wherein,

Figure l isa perspective view of an outlet" or junction box embodying this invention, Fig. 2 is a cross section on the line 2, 2,' in

' Fig. 3, Fig. 3 is a sectional plan view of a box, part of the cover being removed, Fig` Il is a face view, and Fig. 5 is an edge view, of the cap or plate for closing the openings in the flange of the cover, Fig. 6 is a detailview of a portion of the cover looking from the under side thereof; Fig. 7 is 'a detail side view of a portion of the cover, showing its detachable cap or plate in position, and Fig. 8 is a detail section taken substantially on l the line 8, 8, in Fig. '3, lookingin the direc tion of the arrows.

Similar numerals p of reference indicate corresponding parts 1n the several views.

The box 1 may be of any suitable construe tion and is shown provided with a bottom, and with side walls l@ having outlet openingsV at 11J withY which suitable conduits 2 ,may be connected. In the example shown the conduits 2 are of well known channel form, and 'adapted to fit at their ends in pockets'or recesses 3 formed in the box l, and said conduits areshown of the class having removable covers 4 which may be held upon the conduits by sliding -in opposed grooves 2, or in any' suitable manner. The general construction of the box l shown in the drawings is of the class, illustrated in Letters Patent for outlet or junction box, issued to us July 27, 1909, No. 929,097. The cover 5 has `a dependent flange or rim 5, adapted to fit over and inclose the box l, as illustrated in Figs. 2 and 3, and said flange or rim is provided with openings 5b adapted to aline .with the openings lb in box 1,the openings 5b in flange 5a being shown extending through the lower edge thereof. At 6 are caps or plates adapted to fit over or within the openings b-of the flange 5 so'as to normally close the same and thereby close the openings l of the box when the cover is thereon. Means are provided to detachably connect caps 6 with flange 53,-and for this purpose said caps are shown of ,width greater than the width of openings 5b so as to rest at their edges against the edges of said openings, and said caps are provided withdugs or ears 7, shown stamped out or formed with the materialof the caps 6,1and said lugs or ears are shown bent back through the openingsA 5b and against the inner surface of' ilange 5a so that the marginal portions of the caps and the lugs 7 will conjointly act to deta'chablyl retain the caps in place. -The lugs or earsmay be suitably bent when'the caps 6 are made sothat by simply sliding the caps into place through the lower open parts of openings 5" they may be attached to and detached from flange 5a. To retain the caps 46 in place against inadvertent removal said caps are shown provided with extensions 8 adapted to Patented June 16, 1914.

co-act `with projections 9 'upon cover '5' or Depending from the cover 5 are lugs 5y alined with the openings 5b of flange 5a and in position to be engaged by theV covers 4f of jg i 1,099,986

the conduits to prevent said 'covers from being pushed too far in box 1'.

The cover 5 may be removably held upon box l by screws l entering threaded holes ll in the box,` or in any other suitable manner.

The box land its cover With flange `5al 'h maybe made of cast metal, and the caps` or closures 6 may be stampedv out of sheet metal, and When completed the caps may be fitted upon the flange and the cover secured over. the box. Vv'hen connection is to be made With conduits the cover 5 Will ibe removed from the box and the conduits fitted in the sockets 3 of the openingslb of the box, and the corresponding caps 6 Will then be removed from the 'flange 5a, and When the cover is attached to the box the openings 5l of flange 5a pass over and receive the conduits 2. The remaining caps Willtlien conceal and protect the holes 1b in the box to which conduits have not been fitted. When any other conduits are to be attached to the box the cover may be 'removed and the corresponding cap detached and the cover replaced in the manner stated.

By means o f the arrangement described an outlet box may be provided that is ellicient in use, in which the caps `for the out-y let openings'inay be readily reiioved With;

lout requiring the breaking away of any integral part of the box or cover, and thereby 'danger of injuring the saine is-avoided.

This invention is not limited to the details shown and described as they may be varied Without departing from the spirit of the invention.
